MEASURING VESSEL FOR LIQUIDS.

Specification of Letters Patent.

To all whom, it may concern:

Be it known that I, HUGO CARL DEHN, a subject of the German Emperor, and a resident of Hamburg, Germany, have invented certain new and useful Improvements in Measuring Vessels for Liquids, of which the following is a specification.

This invention relates to improvements in measuring vessels for liquids of the class which in the known manner consist of two or more divisions or chambers, which are connected with a larger reservoir (for example, a transportable tank) and with each other by means of a valve or cook in such a manner that liquid flows into one of the divisions of the vessel out of the reservoir when one other and previously-filled division is emptied. As each of the compartments is adapted to receive a certain quantity of the liquid, the vessel may be employed for measuring quantities of liquid delivered for the purpose of sale, for example. The employment of devices of this kind for the public sale of petroleum, milk, or the like from large transportable vessels has hitherto been restricted, because known appliances of this kind for measuring liquids have not been adapted to be gaged or tested, so that they could not legally be used for effecting public sales. In order to obviate this limitation that is to say, in order to render such appliances capable of being testedthe following arrangement is adopted in accordance with the present invention.

In the accompanying drawings, Figure 1 is a central vertical section of a measuring vessel for liquids with two divisions or chambers constructed in accordance with and embodying my invention; and Fig. 2 isa plan, partly in section, of the said liquid-measuring vessel.

Similar letters refer to similar parts throughout both views.

The measuring vessel A, which is divided into two compartments a a is rotatably mounted by means of an ordinary solid upper trunnion b and a lower trunnion 0, which constitutes the plug of a two-way cook. The said vessel A commuicates with a larger reservoir d by means of conduits or passages in such a manner that one compartment, as shown in the drawings the compartment or, may be caused to communicate with the reservoir d through a passage 0 and a conduit 6 for liquid, also a conduit 1) f for air through a cock-passage 0 and a conduit h with the reservoir (Z, while the other compartment a maysimultaneously be caused to communicate, through a passage 0 in the cock-plug, with the fixed discharge-spout g of the cock, and through an air conduit 72 a passage 0 in the plug of the cock, and a passage if in the cock-casing with the outer air in order that one compartment may be filled and the other emptied in the known manner. The rotation of the divided measuring vessel A may be effected by the intermediary of a handle 2', arranged upon the vessel, and limited at the proper moment by suitable stops in is. -This measuring vessel is rendered capable of being gaged, and therefore adapted for effecting public sales, owing to the fact that the outlet g is provided in the plane of the bottom of the effective measuring-chamber and each compartment or measuring-chamber at the highest point of the effective measuring-space with sight-holes or inspection-windows of a special arrangement. The provision of an inspection-window merely in the cover of each measuring-chamber a a has proved to be insufficient, as such a window only permits of inspecting the surface of the liquid, and such an inspection does not permit of determining its exact height. Accordingly each inspection-window or pair of inspection-windows Z Z is arranged laterally on the measuring-chamber or, strictly speaking, laterally on dome shaped upper continuations m, into which the two air-conduits Z) 5 partially extend. The domes m inclose the air-conduits without too much play. In this arrangement the upper edge or rim of each air-conduit 6 6 forms a gage to which each chamber or compartment must be filled in order to deliver the proper quantity of liquid. When the liquid flowing out of the reservoir cZ into one of the chambers has reached the upper edge of the said air-conduit, it flows into the air-conduit, which is here utilized as overflow, and the admission then ceases. Should any failure occur in the correct filling of a chamber, itmay be ascertained through one of the upper sigh tholes or inspection-windows, and, further, (and this is-an especially important point,) the upper edgeof each air-conduit, which edge corresponds with a gage-mark on the inspec tion-window, also remains properly utilizable as a gage when the measuring vessel assumes an inclined position, because the level of the liquid presents so small a superficial extent beside the gage edge within the dome m that when the level extends to this gage edge the quantity of liquid contained in the chamber may always be taken to be the same, whether the measuring vessel is situated in an exactly upright or in a somewhat inclined position. It is only owing to this provision that it is possible to arrange the measuring vessel upon a transportable tank, so that it may be used in a form that may be gaged or tested for the sale of petroleum, milk, or the like in the streets, as the small inclination of the vessel, which is unavoidable under such circumstances, in'no wise affects the exactness of themeasurement. Thelowerinspection-window Z shows whether the whole of a measured quantity of liquid has been run ofl.

When the measuring vessel A is rotated so as to bring one of its compartmentsfor example, the compartment a/in communication with the reservoir or tank (Z, liquid will flow into the said compartment and force out the air contained thereinthrough the dome m, the air-conduit Z2 f, the passage 0 air-conduit h and its additional pipe 0 into the tank cl under a hood or cup 19, arranged over the upper end of the pipe 0 and provided with two partitions p p of wire-gauze or the like. This cup 10 prevents the liquid of the tank from flowing into the air-conduit leading to the compartment (4. When the compartment (0' has been filled with the proper amount of liquid-that is to say, when the level of the liquid in the compartment a is flush with the upper end of the pipe 5' or mark on the inspection-windowany additional liquid which may enter into the compartment will flow into the conduit Z), so that always the determined amount of liquid is secured Within the compartment a. While the compartment a is being filled the compartment a is in such position that its contents fiows out through the passage 0 and spout 9, communication being established at the same time between the interior of the uppermost part of the compartment a and the atmosphere by means of the air-conduit 6 f passage 0*, and air-conduit If, so as to allow of external air to enter the compartment (0 After the compartment a has been emptied the vessel may be turned into such position that neither of the compartments a a is in communication with the liquid-conduit e and spout g or that the compartment a is in communication with the spout g and air-channel k in order to be emptied and the compartment (0 in communication with the liquid-conduit e and air-conduit it in order to be filled anew.
